Truck quit and won't start.
I primed it and it will start and keep running as long as I keep putting gas down the carburetor. So it is getting spark just not fuel.
I changed the relay, and the fuel filter. Still no start. Almost full tank of gas.

Good afternoon,

Can you check the power to the pump to verify the power?

If you have power, the fuel pump is bad. If there is no power, then we need to do some testing.

I disconnected the fuel pump right at the pump and checked for power there. There is power getting to fuel pump.
After I connected the pump back up the truck started but ran rough and then quit.

Okay, if it started there had to be power to the pump.

You will need to check the actual pressure. You can rent a tester at a parts store. You will need to T into the fuel filter for the test.
